Transcribed Image Text:A pair of parallel helical gears
consists of a 20 teeth pinion meshing with a 100
teeth gear. The pinion rotates at 720 rpm. The
normal pressure angle is 20°, while the helix angle
is 25°. The face width is 40 mm and the normal
module is 4 mm. The pinion as well as the gear is
made of steel 4OC8 (S
treated to a surface hardness of 300 BHN. The
service factor and the factor of safety are 1.5 and
2 respectively. Assume that the velocity factor
accounts for the dynamic load and calculate the
power transmitting capacity of gears.
